小学算术教学大纲（修订草案）开首就明确的指出：“小学算术教学的目的，主要是使儿童能够自觉地、正确地和迅速地进行整数运算，能够运用已经获得的知识、技能和技巧去解答算术应用题和解决日常生活中简单的计算问题。”我认为正确地和深入地了解它，是很重要的。 At the very beginning of the primary school syllabus (Revised Draft), it was stated explicitly that “the primary purpose of arithmetic teaching in primary schools is to enable children to perform integer arithmetic consciously, correctly and expeditiously, to apply the acquired knowledge, skills and techniques Answer math application questions and solve simple computational problems in everyday life. ”I think it is important to understand it correctly and in depth.
